The operating temperature range of -40°C to 85°C covers industrial environments — think outdoor telecom cabinets, factory-floor instrumentation, or HVAC controller boards that see seasonal extremes. ## Input configuration and reference — two decisions that matter The input type can be set as differential (one channel) or single-ended (two channels). Differential mode rejects common-mode noise on long sensor leads — useful for thermocouple or bridge-type measurements where the signal is small and the environment is electrically noisy. Single-ended mode doubles the channel count for monitoring multiple DC voltages (supply rails, potentiometer wipers, panel-mount sensors) without adding an external mux. ## Lifecycle and compliance — active, no obsolescence concern The MAX11644EUA+T is listed as Active with ROHS3 compliance. For new designs or production replenishment, the part is available through independent distribution and can be quoted to order.","metaTitle":"MAX11644EUA+T ADC, 12-Bit SAR, I²C, 8-uMAX/uSOP","metaDescription":"Maxim Integrated MAX11644EUA+T 12-bit SAR ADC, 94.4k sampling rate, I²C interface, differential/single-ended inputs, internal/external reference, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Input Type":"Differential, Single Ended","Architecture":"SAR","Configuration":"MUX-S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"I²C","Number of Bits":"12","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Reference Type":"External, Internal","Ratio - S/H:ADC":"1:1","lifecycle_stage":"eol_hot","Number of Inputs":"1, 2","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"8-uMAX/uSOP","Number of A/D Converters":"1","Voltage - Supply, Analog":"5V","Voltage - Supply, Digital":"5V","Sampling Rate (Per Second)":"94.4k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.43","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.43000","currency":"USD"},{"qty":10,"price":"$3.07700","currency":"USD"},{"qty":25,"price":"$2.90880","currency":"USD"},{"qty":100,"price":"$2.52100","currency":"USD"},{"qty":250,"price":"$2.39168","currency":"USD"},{"qty":500,"price":"$2.14604","currency":"USD"},{"qty":1000,"price":"$1.80992","currency":"USD"},{"qty":2500,"price":"$1.71942","currency":"USD"},{"qty":5000,"price":"$1.65478","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/MAX11644-MAX11645.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX11644EUA+T have an internal reference?","answer":"Yes, it supports both internal and external reference options, selectable via configuration.
